I try to use the file pg_type.h who containing, pre-defined type like INT4IOD, INT2OID, INT8OID.
So I include in the file #include "server/catalog/pg_type.h" but I have the followed error C:\Program Files\PostgreSQL\8.3\include\server/catalog/pg_type.h(22) : fatal error C1083: Cannot open include file: 'nodes/nodes.h': No such file or directory
